Reservoir Care & Cleaning:

  • Fill reservoir 1/2 full with warm water and mild soap. Use 2 tablespoons of baking soda, bleach or CamelBak® Cleaning Tabs for a deep cleaning.
  • Shake reservoir to mix water solution.
  • Elevate the reservoir so drink tube exit port is at the base and Big Bite™ Valve is below the reservoir.
  • Pinch bite valve, allowing solution to flow into drink tube, and through the bite valve. For a deep clean, let reservoir and solution sit for 30 min.
  • When deep cleaning: remove solution and repeat using warm water/ mild soap solution.
  • Wash reservoir. You can use CamelBak® brushes from the Cleaning Kit to scrub the reservoir and tube. When deep cleaning, make sure you completely rinse away any bleach or cleaning solution.
  • After washing, rinse away cleaning solution in the reservoir and drink tube.
  • Drain all remaining water. The reservoir is ready to use.
  • If storing, air dry reservoir with Reservoir Dryer™ accessory so no moisture is trapped inside.


Pack Deep Cleaning:

  • Soak it in warm or cool water with some mild soap.
  • Rinse it thoroughly with cool water (skip this step, and you might end up creating some suds the next time you sweat with your pack on).
  • Hang it up to air dry.
